For maize, fully expanded third leaves of wild type (WT) and lox10-3 mutant in the B73 background were enclosed in 800 mL jars (one leaf per jar) alongside a cotton ball containing 2.5 μL of 100 mM of select PLVs dissolved in dichloromethane. For Arabidopsis, intact WT or Atlox2-1 mutants were grown in small pots (∼350 mL) (5 plants/pot), were enclosed in these jars with the respective treatments. Col-0 was exposed to 5 μL of treatments, Atlox2-1 mutants were exposed to 2.5 μL. Four replicates for each plant/genotype/treatment were used. PLV treatments included purified chemical standards of (2Z)-pentenol, (2E)-pentenol, (2E)-pentenal, pentanol, pentanal, 1-penten-3-ol, 1-penten-3-one, 3-pentanol, and 3-pentanone (Sigma-Aldrich, St. Louis, MO, United States). Plants were incubated alongside the PLV treatments for 20 min, and then volatiles were collected onto HaySepQ filters containing 80–100 mesh (Supelco, Bellefonte, PA, United States) via dynamic airflow (1 L min–1) for an additional 20 min. Volatiles were eluted off the HaySepQ filter traps with 250 μL of dichloromethane containing 100 μM of the internal standard, (4Z)-hexenol (Sigma-Aldrich, St. Louis, MO, United States). Volatiles were analyzed and quantified via gas chromatography mass spectrometry (GC-MS).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
